摘要：

We generalize experimental data on the low-cycle durability of 22K steel and its welds, i.e., materials of which the steam separators of nuclear power plants with RBMK-1000 reactors are made. These experimental data are compared with the reference curve for carbon steels according to the Standards PNAE G-7-002-86 currently in force. We show that the values of safety factor are provided in the assessment of the cyclic strength of separators made of 22K steel. Hence, the service life of the equipment of nuclear power plants of the first generation with RBMK-1000 reactors made of 22K steel can be extended for 15 years.
